The rivets of aluminum and Jinmen are riveted by electric drill and rivet gun. Bit hardness should be high, or choose a special reamer. When drilling, in order to ensure the accuracy of drilling position, it is suggested to drill a small hole in aluminum to facilitate positioning operation. If the aluminum is thick, it should be cooled with clear water before drilling.

When purchasing aluminum alloy materials, you can choose from its thickness. The general national standard is 1.4mm, but in real life, the thickness of 1.0mm can meet the needs of the owners. Of course, if you want to choose a good sound insulation effect, it is recommended to choose a thicker aluminum alloy material.

Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements, and it is one of the light metal materials.

Aluminum alloys are divided into forged aluminum alloys and cast aluminum alloys according to their composition and processing methods. Deformed aluminum alloy is made by melting and casting alloy components into ingots, and then plastic deformation processing is carried out, and various plastic processed products are made by rolling, extrusion, stretching, forging and other processes. Casting aluminum alloy is to melt the ingredients and directly cast them into blanks of various parts through sand mold, iron mold investment and die casting.
